Drill floor surface pipe column processing manipulator

The invention provides a drill floor face pipe column processing manipulator. Comprising an L-shaped base arranged on a drill floor surface, a walking track fixedly arranged on the top of the base in the direction of the base, a walking mechanism horizontally installed on the walking track in a sliding mode, and a mechanical arm body which is rotationally installed on the top of the walking mechanism, can do linear reciprocating motion in the horizontal direction and clamps a pipe column. The two vertical sections of the walking track are an operation section and an avoiding section respectively, a rotating section which can be in butt joint with the operation section and the avoiding section through rotation in the vertical direction is arranged between the operation section and the avoiding section, the operation section is arranged between the two three-joint unit areas, and the avoiding section is arranged on the sides, close to the center of a wellhead, of the three-joint unit areas.
